Introduction

The AO250 model is a highly economic digital IR pyrometer with extended sensor head and separate
electronic box for non-contact temperature measurement of metals, ceramics, graphite, etc. in
temperature ranges between 250 °C (482 °F) and 1800 °C (3272 °F).

The AO50/50H model is a specially designed digital pyrometer in 4 wire technology with extended
optical head which can withstand high ambient temperatures up to 120 °C (248 °F) and 180 °C (356 °F)
(AO50H). It has a inbuilt LCD & keypad for parameterization to provide high performance and low
maintenance of non-contact temperature measurement for a demanding industrial environment.

Application, Range and Working Principle

2.1

The OSAO-Series pyrometers are especially designed for industrial purposes. The AO250 model is
suitable for high temperature measurement ranging from 250 °C (482 °F) to 1800 °C (3272 °F). The
AO50/50H pyrometers are suitable for high temperature measurement ranging from 0 °C (-32 °F) to 800
°C (1472 °F).

OSAO-Series IR Pyrometers are two-piece measurement systems containing one extended sensor head
and one electronic enclosure. The enclosure comes with built-in 4 digit LCD display and offers many
signal processing features. The Keypad on the enclosure helps set the following parameters: Emissivity,
Analog Sub range, Relay Setpoint and Hysteresis, Analog Output, Temperature Units, Response Time,
Peak Picker and Sensor Address. The sensor head is un-effected by electromagnetic interference.
Using the serial interface and provided software temperatures can be displayed and logged to a
personal computer. The software can also be used to configure the unit parameters.

The AO250 model has response time of 2 msec adjustable up to 10 seconds. The instrument can be
powered directly through the USB without any external power supply.

The pyrometer temperature measurement method utilizes the fact that objects emit thermal radiation
in an amount that directly corresponds to their own temperature and surface emissivity.

The pyrometer sensor detects the amount of infrared radiation emitted by the measured object (target).
The infrared signal and temperature representation is then analyzed by built-in microprocessor.

The applications for the OSAO-Series:



Plastic & rubber



Ceramic



Paper



Textile



Fluids

Setting at the instrument

User can power up the unit either by USB input or by using connection cable at 24V DC input.
After power up sensor starts an initializing routine for some seconds. After this the object temperature
is shown in the display. User must remove the screw (mark USB in figure) to connect the unit with PC via
USB cable.

4.1 Operation

The programming keys FUNC, UP and DOWN enable the user to set the device on-site. Normally,
LCD shows temperature or error. To view different parameter FUNC key is pressed repeatedly. To
change values of parameters UP & DOWN keys are used. After changing values in any parameter by UP
& DOWN key finally FUNC key should be pressed to save that value in device. If FUNC key is not pressed
after changing parameter value than device will automatically take the old value & device will start
showing temperature. If any key is not pressed for more than 5 seconds than device will automatically
show the temperature.

For targeting LED light is provided in device (AO250 Model Only). Press UP + DOWN key
simultaneously to change the present condition of LED (ON / OFF).

4.2 Adjustable parameters

Emissivity: It is the relationship between the emissions of a real object and the emission of a black body

radiation source at the same temperature. For a correct measurement it is necessary to adjust emissivity.
Emissivity depends on the surface condition of the material, the spectral range of the pyrometer and the
measuring temperature. Different material has different emissivity ranging from 0.1 to 1.0. User can
change emissivity by given keypad on the instrument.

Set point : Instrument is equipped with a relay contact controlled by the measuring signal. The relay set
point is adjusted within the measuring range. The relay contact is “OPEN” below set point value and
“CLOSED” above the value.

Page |

8

Hysteresis (Hyst.): The relay contact closes when temperature exceeds the set point. It opens only if
the temperature falls below the value which consists of set point and the adjusted hysteresis. It can
be adjusted from 2 °C (35.6 °F) to 20 °C (68 °F).

Example: if the set point value is 500°C and Hysteresis is set at 10:

1. Relay contact is OPEN below 500°C

2. Relay contact will CLOSE above 510°C

3. Once CLOSED the relay contact will OPEN again when temperature falls below 490°C.

Ana. Sub range LO: Analog sub-range is adjustable within the basic range, user can set low analog
sub-range here.

Ana. sub range HI: User can set the analog sub-range high value here. Minimum span between lower &
higher value is 51°C.

Analog output: User can select the output from 4…20mA or 0…20mA or 0…10V and T/C K-type or J-type

for AO50/50H Models

Temp. Unit: User can select °C or °F unit.

Sensor address: For communicating with pyrometer via software users have to give an address. The

address may be 1 to 255.

Response time: The response time can be set according to specified response range of device.

Picker: Please refer to chapter 7.

Head temp: displays the temperature of head.

Internal temp: displays the internal temperature of pyrometer.

Optics

The pyrometer measures temperature by receiving heat radiation from the object whose
temperature must be measured. This heat radiation is passes through the lens to the sensor and is then
converted to an electrical signal. The farther the measured object is from the pyrometer, the larger the
area that will be measured by the pyrometer. Depending on customer needs, the pyrometer is
designed for different FOV. User must select the FOV when ordering.

Contamination on lens will cause inaccurate temperature reading therefore an air purge
unit can be used for sensor head. Cleaning with dry cloth is sufficient for lens cleaning.

5.1 Optical specification (AO50/50H Models)

*FOV mentioned on the pyrometer.
For example: If pyrometer FOV is 15:1, then spot size at 1500mm calculated as given below method
except that minimum spot should be 6mm.

5.2 Optical specification (AO250 Model)

* Manufactured working distance (WD) mentioned on the pyrometer.

Page |

11

If the pyrometer is not installed at manufactured working distance (WD) then spot size at actual
installed distance should be calculated. For example, if factory made working distance is 300mm and
pyrometer OS-AO250-201-300 (350°C (662 °F) - 1800 °C (3272 °F)), then spot size is 3.8mm (as given in
table). If user installed this pyrometer at 600mm then spot size is not 7.5mm (as given in table), user
should calculate using the following:

4.2.2 Temperature

It shows the temperature measured by the pyrometer

4.2.3 Parameter Setting

All user selectable device parameters can be set by using the software in the Panel "Parameter"

(A) Emissivity settings The emissivity can be set by clicking on

"Parameters” and select or type in the desired emissivity
directly in the description field. The emissivity value will be
transferred to pyrometer by hitting the "TAB " button.

(B) Response time The desired response time can be chosen in

the panel Parameter by clicking the appropriate list box (as per
the values available in the drop box of response time). This
parameter is used to set the analog response time of
pyrometer.

(C) Sub Range Begin & Sub Range End User can change the sub

range of pyrometer in the panel Parameter. Sub range must be
within the basic range of pyrometer, the minimum span
between higher & lower range is 51. Analog output will be
automatically set according to the sub-range by clicking the
"TAB" button.

(D) Sensor Type Shows pyrometer sensor type. User can

change sensor type from two color to single color and vice
versa (only applicable with two color pyrometer).

(E) Switch off level% (for two color pyrometer) This function

is used to avoid measurement errors caused by signals which
are too low. Although factory default is set to 15 %, the
switch off limit can be adjusted between 2 and 50%.

(F) Unit User can change the measuring unit of temperature

from “Centigrade" to “Fahrenheit" and vice versa.

Page |

17

(G) Peak Picker Setting Three Pickers are available in Pickers setting menu

(Auto, tCL, Smart). User can switch on any as per requirement, one at a time.

(G1) Auto “Auto” mode is used for discontinuous measuring task, such as
object being transported on a conveyer belt in such a case the maximum
value for each object has to be indicated. When the object passes the
measuring beam of the pyrometer, the maximum value is stored until a new
hot object appears in the measuring beam. The temperature which has to be recognized as “hot” is
defined by the low limit of the adjusted sub range. The stored maximum value will be deleted when the
temperature of the new hot object exceeds the low limit of the sub range by at least 1°C. If a lower limit
is not entered, the maximum value storage will be deleted whenever the low level of the full
measurement has been exceeded.

(G2) Clear time (tCL) If the peak picker is switched on, the last highest temperature value will always be
displayed and stored. As such, it may be beneficial to periodically clear and reset the stored values in
order to obtain new temperature readings.

Example: If we set the tCl at “6 sec” the last highest temperature value will be display for 6.0 sec to 12
sec then it will capture next pick.

The following settings are possible:
OFF: With clear time “OFF” the maximum value storage is switched off and only momentary values are

measured.

tCL (10msec...25sec): Clear Time tCL can be set between 10msec and 25sec. When set, estimates the
maximum value and holds it in buffer memory. After the entered time, the storage will be deleted.
Clear Time feature is particularly useful when object temperature is not uniform across its dimension or
the pyrometer is not constantly viewing an object to be measured. The peak picker works with two
buffer memory locations to find maximum value over a defined interval. With the first memory
location, the highest measured value is held and is deleted alternately in the time interval set (clear
time). The other memory location retains the maximum value throughout the next time interval. The
disadvantages of fluctuations in the display with the clock frequency are thereby eliminated.

Page |

18

Note:

The maximum value storage coincides with adjustments made to response time. Therefore:
(I) Clear time<= the adjusted response time is useless
(ii) Clear times must be at least 5 times longer than the response time.
(iii) Only maxima with full maximum value can be recorded, which appear at least 5 times longer than
response time.

(G3) Smart If the smart picker is switched on, the highest last temperature value will always be
displayed and stored. This feature is particularly useful when object temperature is not uniform across
its dimension or the pyrometer is not constantly viewing an object to be measured.

Smart Picker Functions

Smart picker can be turned ON & OFF by using the software. When Peak picker is ON, the peak
picker menu is enabled for setting of the parameters like decay rate function, reset below
temperature and peak picker delay.

(I) Decay rate The Decay rate range is 0.00 to 166.66°C/sec. or 0.00 to

300°F/sec. depending upon °F/°C unit’s selection. The slowest Decay rate is
0 degrees per sec. This feature helps to eliminate erratic measurements
and allows the peaked value to decay down to lower process temperature
values as they occur. Decay rate is set to retain peak measured
temperature value and ignore momentary decreases in measured
temperature.

(ll)Delay Time This function sets the delay time in sec. before peak picker
function starts. The delay time is selectable in the range of 0.02 to 10.00
sec. Zero (0) turns delay time OFF. This function is used to delay the start
of peaking action for up to 10 sec. following the detection of leading edge
of a new target.

(lll) Reset Below Temperature (RBT) The user can set RBT within the limit of pyrometer sub range.
This function sets the temperature above which peak picker action starts. When the target
temperature matches or is below the selected value, the sensor indicates temperature without picking
action.

(H) Relative energy (for two color pyrometer) The relative energy shows a signal weakening which

can be caused by contaminations of the optics, viewing window or dust in the field of view.
Measuring objects that are too small will also weaken the signal. Relative energy shows the measured
intensity compared to the intensity a black body radiation source would have at a determined ratio
temperature of the pyrometer.

(I) Analog Range User can select the analog range from the options available.

(J) Comm. Mode User can select the communication mode as per requirement.

Note: To view parameters of multiple devices select the pyrometer name from the drop down list that appears at the

top of the screen.
